AZ 1 = Adventure Zone 1 = the entire world map campaign playing area at the moment. When there will be more content, a new zone will presumably be added to the world, and this would be Adventure Zone 2 and would drop AZ 2 packs. And so forth.

I have a neat one - for whatever reason, if you use battle as an orc warrior, with Zoltog out, and hit the opponent with that battle, it will create a savage raider. May be a bug (Zoltog specifies troops dealing damage) but it is definitely a neat synergy currently.

As an Elf Warrior, with no Elves on board, I've had the Stirring Orration with equipment recur. Not once, but multiple times.

Hmmm...interesting. I hope that's intentional and not just a bug. Old cards like that triggering off of your champions class/traits would be really cool. Hope it stays that way!

I agree, we need more race interactions between cards and the champion. We already have interactions between the class and card classes but not many reasons yet to stay true to the race, which means people just take whatever race is best for the class they want to play and build whatever deck they got in mind.
